I did purchase my first bus on Ebay. I actually pushed the "Buy it Now" button for $150k! (still only gives you one point on your profile!)
But, I had called the seller, and indicated it was conditional on me flying up, seeing the bus, and approving.
I also purchased a $50k Corvette on Ebay too. So, here it is, I had purchased $200,000 worth of goods on Ebay, and I had a positive score of 2!
